opening and no other opening, and it is de-' sirable that this grease should be periodically removed in order that the casing may be filled W1th new, clean grease. In the trans- "mission and differential casings for automo biles, for instance, a'heavy. grease is used, and it is almost impossible through the use of such tools as were known before the present invention to remove the grease from these casings. The-object of the present invention then is to provide a device through the use of'which grease or similar material may be removed from such casings. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a side elevation ct my device; and Fig. 2 is an elevation, partly in section, clear- 1y showing the conveyor means whereby grease may be drawn from a casing in which it has been packed.

My tool consists essentially of a casing 1 and a handle 2, the casing providing a motor receiving recess 3 in which a motor r is mounted, the hubs 5 of the motor being received in aligned journals 6 provided interiorly oi such recess. Packing 7 and8 is provided to prevent the grease from being forced into the motor receiving recess 8.

The hub 5 of the motor is provided with a spindle ,9 having a reduced screw-threaded end 10 and which extends through an aperture '11 in the wall of the recess 3 and into the opening 12 of the passage 13. The hub 5 is provided with a similar spindle 14 having a reduced screw-threaded end 15 and projecting through a similar aperture 11 into spaced apertures 25. the flexible worm conveyor 26 which carries opening of the passage ii". The passages 13 and 17 are connected through a tube 18 "which is held. in position in the adjacent 1b, as at22, is a rigid curved intake tube 23,

having a closed end 24-. and being provided ad acent its closed end with peripherally The tube 23 encloses at its inner'end a member 2? provided with a screw-threaded socket 28 in which the reduced screw-threaded end 15 of the spindle I Q 1s is engaged.

Threaded into the opening '12 of the passage 13, as at 29, is a coupling member 30,

to the free end of which is attached in a well.

known manner, one end ot a flexible tube 81 enclosing a worm conveyor 32 whichcarries at ltSlIlllGl end a member 27 similar to that carried by the conveyor 26, and having a similar socket 28 in which is engaged the reduced end 10 of the spmdle 9. The tube 31 carries at its free end a discharge nozzle 33.

The handle 2 is rigidly connected to the casing 1 by means of machine screws 34:. This handle is made up of two sections secured together by means of screws or similar fastenings 35, and interiorly o'tthe handle there are provided terminals to which the ends of the conductor 86 carrying the usual screw socket plug 37 may be attached. Terminals are also supplied on the motor, and connection between the handle terminals and the motor terminals. is effected through a switch in the handle which includes a projecting operating button 38. This button is conveniently located on the handle in such a position that it may be operated by one finger oi the hand in whcih the operator carries the handle of the lubricant transferring device. In operation, the device is gdpped by the handle 2 and the tube 23. is inserted through al 53d and carried by the conveyor into the opening 16 of the passage 17. As more grease is carried along the tube 23, the grease in the passage 17 is gradually forced through the tube 18 and into the opening 12 of the passage it Where the conveyor 32, which is being rotated through the connection of the spindle J with its member 27, picks up the grease and forces it on through the flexible tube 31 and iinali out oi the nozzle and into a container provided tor the reception of the waste grease.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made regards the mechanism herein disclosed, provided the means stated by any 01 the following claims or the equivalent o'l" such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:

1. A device of the class described, comprising a casing providing an intake and an outlet, a Worm conveyor in said intake, and a motor in said casing connected to saidwvorm and-adapted to rotate the same.

2. A device of the class described, com prising a casing providing an intake and an outlet, a Worm conveyor in said intake, a Worm conveyor in said outlet, and a motor in said casing and connected intermediate said Worms to drive the same.

A device of the class described comprising in combination, a casing having therein a motor receiving recess and a passage around said recess terminating at the respective ends of said casing in aligned openings, a rigid curved tube leading from one of said openings, a flexible tube leading from the other of said openings, a Worm conveyor in said rigid tube, a motor in said motor receiving recess, and driving connections between said motor and said Worm.

4. A device of the class described comprisingin combination, a casing having therein a motor receiving recess and a passage around said recess terminating at the respective ends of said casing in aligned openings, a rigid urved tube leading from one of said openings, a flexible tube leading from the other oi said openings, a Worm conveyor in said ri 'id tube, a motor in said motor receiving recess, contact terminals on said motor, drivconnections between said motor and said Worm, and a handle member attached to said casing, anelectrical conductor leading from contact terminals in said handle and adapted to be conni-rcted to a source of electrical supply, and electrical connections between said handle terminals and said motor terminals and extending through a switch mounted in said handle for operation by the hand in which the operator holds the handle.

5. A device of the class described comprising in combination. a casing having a motor receiving recess, a motor in said recess, a handle attached to said casing and carrying a switch for controlling said motor, journals in op lite ends oi 'd motor receiving recess, hubs extending Irom opposite ends of said motor and mounted in said journals respectively, passage in said casing, terminating in opcni gs at opposite ends of said casing, said openings being aligned With each other and with said journals, a rigid, curved tube mounted in and extending from one of said o 3enings, a Worm conveyor in said tube, a flexible tube mounted in and extending from the other of said openings, a worm c0nveyor in said tube, a screw-threaded spindle extending from each oil: said motor hubsand into said respective openings, and a screwthreadec socket on the inner end of each of said Worms and threadedly engaged With one of said spindles.
